CONRAD HARRIS AND PAUL W. ZOINER, OF CINCINNATI, OHIO.

Letters Patent No. 99,565, dated February 8, 1870.

DOOR I'OR CANNON STOVE. r

The Schedule referred to in these Letters Patent and making part of the same VVQCONRAD HARRIS and .PAUL W. ZOINER, both of Cincinnati, in the county ot'Hamilton, and State of Ohio, have invented a new and useful Ash-Pit Door for Cannon Stoves.

Nature and Objects of the Invention.

Our invention consists in the employment or use, for the lower or ash-pit door of cannon or other stoves, of circular horizontal section, of an unbroken annulus or band, perforated correspondingly with the stove, a'nd'so supported as to revolve freely thereon, whereby great nicety of regulation is attained, with superior cleanliness and neatness in appearance, and any separate register is dispensed with.

Description of the Drawing.

B and C are'the entrance-apertures of the fire-place andash-pit, respectively. I

D is the fircdoor, and E is the ash-door.

Each door is adapted to revolve on a suitable ledge,'

F or G, but instead of being only a segment of a. cone or cylinder, as the case may be, each door is formed of an'undivided circle, which surrounds the body of the stove.

Each door is pierced with an aperture, (1' or e, which apertures correspond with those of the fire-place and ash-pit, respectively, and the doorin each case is.

opened by being revolved until its aperture is brought opposite that .of the body of the stove.

Several very striking advantages result from this form of doors, among which maybe cited, each door being a complete circle, presents no unsightly ends, liable to warp or to be broken off; a much more agreeable finish is imparted to the stoveyeaciidoor is seecuredby simply dropping it in-place in the act of putting up the stove, and remains securely in place, while it is at the same time capable of being easily opened and shut, there being no disposition to bind or jam, as

aften occurs with slidc doors of customary construction.

In addition to the above advantages, the form,'as applied to the ash-pit door, is peculiarly beneficial, owing to the perfectmeansit affords for regulating the draught, rendering unnecessary the unsightly supplementary register now employed.

We are aware that annular revolving doors have been employed to close, the fuel-openings of stoves. We, therefore, do not claim such; We are also aware that rotary perforated annuli have been employed to govern thewihdows of illuminated stoves. These we do not employ.

\Ve preferably employ the annular fire-door, (which is. public property,) but do not confine ourselves thereto. a

Claim.

' We claim as new- An annular door or register, surrounding the has of a cannon stove, for the purpose of regulating the supply of air to the fuel, as herein represented and desclib'ed. p
